Looks like a brick, flies like a brick, has the aerodynamics of a well engineered brick

[tapelegs]

Of course, it's so simple! An enormous, extraneous, heavy, difficult to balance, functionless, and aesthetically horrendous disk!

invenzione idiota.....

genial para llevar la pizza bien pronto...

I can say easily that it is a stolen idea. I am sure that designer was aware of this concept and have seen in internet an example of it and created own design.

There are many quacks stoling other's ideas and presenting as if their own idea.

U.S. already has this, it quiets the sounds of the rotor.

just add telescopic rotor blade

it will be efficient during frontward flight

and also colapse the small rotor blades after the size is decreased it might help getting some lift if mounted the proper way

[BucketandSlash]

so it like really goes from heli to jet thing?

if feel like he came up with this while someone pooped on his chest.

@RentedSpot yeah i realise that. if the rotors arent any good in cruise, its dead weight. and yeah, i know the wings on the 104 are stability. this is why i dont think helos will ever overtake aircraft. the closest we are gonna get is tilt rotor, but the wings are too stuby for the same efficiency

[RentedSpot]

@abhiginimav the f-104 starfighter is pretty much just a rocket with wings. The "wings" are basically just for stability, and cannot really be compared to a conventional aircraft. If the engine quit on the f-104, it is dropping like a brick out of the sky, theres no gliding as you can do with a conventional aircraft. Now for this aircraft, the disk assembly, even if it was shaped as an airfoil, would be extremely heavy to contain the mechanism to extend and retract rotorblades.
